We're already looking at holidays for 2023 after semi successful holiday this year (air bnb and extended family in southern Spain). We've seen Neilson holidays with beach club for kids and activities for DH top secret hobby (aka cycling). Our DD1 will be five years old and has so much energy she is completely outstripping what we can do with her (and we're active people) as we also have current 5 month old DD2 (so would be about 18 months next summer). Not looking for club provision for her but am exhausted and frazzled on this holiday and interested in options to provide a bit more childcare for the four year old (we have GPs with us but they just can't keep up with her) so even if I am with baby it's a bit more relaxing. Have also realised that while I deeply appreciate the help from the GPs we have to entertain them as well as they are both of the we don't mind what we do mindset so we're making all the decisions.
So in summary, somewhere with decent kids club, possibly activities for grown ups but we could organise independently if needed. Babysitting service a plus but not essential. Happy to throw money at the problem within reason.
